SOMERSWORTH — A Somersworth man has been indicted on charges he sexually assaulted a minor and helped another man do the same thing.

Prosecutors allege that 20-year-old Steven Yerakes, of Winter Street in Somersworth, engaged in a pattern of sexual abuse against a child, beginning when the child was 11 and continuing when the child was 12.

The abuse allegedly took place on or between May 12, 2009 and Sept. 5, 2010, according to the indictments returned by a Strafford County grand jury earlier this month.

During that same time period, Yerakes also allegedly brought the child to another man named Mark Rousselle on multiple occasions to help Rousselle sexually abuse the child.

Rousselle was arrested in October 2010. The 45-year-old Somersworth resident was sentenced in July to serve two consecutive terms of 8 to 30 years in prison for alcohol-facilitated sexual assault, according to The New Hampshire Union Leader. He also received another term that was suspended.

Yerakes has been charged with one count of aggravated sexual assault and one count of being an accomplice to the same crime. Both are felonies, and carry maximum sentences of between 10 and 20 years in prison and $4,000 fines.

Yerakes was indicted Nov. 15. An indictment is not an indication of guilt. Rather, it signifies that a grand jury found sufficient evidence to warrant a trial.
